Contreiras & Ribeira da Janela — Reef Mechanics, Channels & Wind Shadow

Two complementary setups side by side: surf low tide on the long left at Ribeira da Janela (up to 2m), then transition to Contreiras as the tide pushes from mid toward high.

起乘警示: 浅礁上陡峭跌落。失误摔倒时请尽量平身向远离暗礁方向弹出。

HYDROGRAPHIC REFRACTION, TAKEOFF & EXIT CHANNEL PROFILE

Beach & Reef Bottom Profile

涌浪形态动力 (海岬浪点 (Point Break)): 10秒以上的长周期涌浪在触及海底火山岩架时立即发生折射，将高达 45 kJ 的波浪推力精准汇聚于起乘区域，且浪壁剥落平整。相邻的深水回流水道排水顺畅，避免冲浪者被暗流拖入落浪冲击区。

1. 进出水域黄金法则

PERSONAL SESSION NOTE: Contreiras works from mid-tide to high-tide (reference session: 10 kt, NNW 331°, 3.6m swell — enter 2 hours before high tide and exit 50 minutes before full high tide). Ribeira da Janela works best at low tide and holds up to ~2.0m.

最高满潮: {tide}m: 1.95m•最低干潮: {tide}m: 0.40m
